Using non Dell Series 9 ink cartridges will give you error messages and may cause the printer not to function.

If you unplug the printer from the wall and remove the power brick for 60 seconds, this will reset any error messages the printer has. I would then plug everything back in.

Power on the printer.

Open the printer(with the power on) and take out the Dell Series 9 black cartridge and then reseat it. I would then take out the color Dell Series 9 ink cartridge and reseat it. Now close the printer and it will print an alignment page.

If you cannot copy a document, the it's tied to the Dell Series 9 ink cartridges. You can try Cleaning Dell ink cartridges. In another thread, members found that if they put tape on the cartridge, where the ink caomes out and insert in printer error message occurs. They then took the tape off and placed the cartridges back in and they started working.

If that doesn't work, then the cartridges will probable need replaced with Dell SWeries 9 ink cartridges.

The odd thing is, the printer prints from the computer okay -- even though the Dell printer monitor sees the (full) black cartridge as almost empty. But the copier, as i say, doesn't copy. What does that suggest -- that PC printing works but copying doesn't?

I used to have a Dell 964 printer that used Dell Series 5 ink cartridges. I have seen the computer tell me that the cartridges were low and the printer said they were full. Reinstalling the printer did correct this issue and may work for you, too.

The printer should have a accurate display of how much ink is in each cartridges.
